SPECIFICATION forming part of Letters Patent No. 632,535, dated September 5, 1899.

Application filed November 1,1898. Serial No. 695,161; No model.)

To aZZ whom it may concern.-

Be it known that LPANAYI'O'HS FKN'O U LIAS, a subject of the King of Greece, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for Dipping Chocolate Drops and Analogous Confections, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to machines for dipping? chocolate drops and other confections in the manufacture of which it is desired to coat the cores or bodies of the same with chocolate or other material in a fluid form.

This invention consists in improvements on a machine for which I applied for Letters Patent April 4:, 1898, Serial No. 676,442; and the object thereof is to furnish a machine for the purpose above described which shall be superior in point of convenience, positiveness of action and efficiency, and which is fully described in the following specification, of which the accompanying drawings form a part, in which like letters and figures of reference refer to like parts in the several views, and in which I Figure 1 is a side view of the machine, showing one of the interior parts in dotted lines; Fig. 2, a top view of the same, partly broken away. Fig. 3 is a side view of the dipping-frame, showing the filling device and the discharging-shelf on an enlarged scale,

Fig. 4 is a plan view of the same. Figs. 5 and 6 are views of details of the same. Fig. 7 is a front end view of the refrigerator and endless apron. Fig. 8 is a rear end view of the same,showing the power-transmitting pulleys for the same and for the power-shaft of the machine. Fig. 9 is a side view of a detail of the driving-gear. Fig. 10 is an end view thereof. Fig. 11 is a side view of a detail of the driving-gear. Fig. 12 is an edge View thereof. Fig. 13 is a sectional elevation of the chocolatereservoir and agitator. Fig. let is a side elevation of the dippingframe in position to discharge the coated candies; Fig. 15, an enlarged detail view of the screw 93 and projection 93 upon the rack 45 and the connected parts; Fig. 16, a side elevation of the dipping-frame in dipped position; Fig. 17, a view of the end of the dipping-frame shaft opposite that shown in Fig. 16, with the connected parts. Fig. 18 is a side view of the cam-bearing end of shaft 19, the cams being partly in section; and Fig.

19, an enlarged plan view of a detail of the refrigerator construction.

Referring to the drawingsmore in detail and to Fig. 1, 18 is the frame of the machine, composed of wood, metal, or other rigid material, and in the front portion thereof and extending from side to side is journaled a main shaft 19. At the front of the machine is pivoted a treadle 20, as at 21, and a cord or strap 20 secured thereto, passes over a pulley 22, likewise secured in the front portion of the frame, and extends rcarwardly to and around a pulley 23, secured to a side piece of the frame and within the same and terminates in a hook 24, which engages a rod 25, which preferably bears at its outer end a roller 26. Upon the shaft 19 within the frame 18 is keyed a collar 27, upon which the roller 26 is adapted to ride during the rotation of the shaft 19, and said collar 27 is recessed, as at 28, to fit the roller 26. Jointed to the rod in proximity to the hook 24: is another rod 29, which extends rearwardly, and the rods 25 and 29 are supported and guided by cleats or slotted blocks 30 and 31. Bearing against the block 31 and surrounding the rod 29 is a coiled spring 32, which bears and exerts pressure against a stop on the rod 29. The outer end of the rod 29 is pivotally connected to a lever 34, which engages pivotally the clutch 35 and also the rigid arm 36, secured to the frame 18. The clutch 35 is mounted on the drivingshaft 37,extendinglongitudinallyofthe frame 18 and suitably journaled therein and bearing at its other end the loose pulley 39, over which runs the main driving-belt H as shown in Fig. 8. The shaft 37 bears at its inner end a worm-gear 41, and it is evident that by depressing the treadle 20 the rod 29 will operate the clutch 35 to throw the shaft 37 into gear with the pulley 39. Any friction-clutch or other suitable clutch mechanism may be employed. The shaft 19 bears rigidly a gearwheel 42, meshing with the worm-gear 41 and mounted intermediately of the collar 27 and the frame 18.

Mounted eccen trically on the shaft 19, exteriorly of the frame, is a cam 43 of oval form, and mounted in the frame 18, forward of and above the shaft 19 and suitably journaled in the frame, is a short shaft 44, which bears on the same side of the frame as the cam 43 a fixed segmental rack 45, and the segmental rack 45 bears a cam 46, which bears at its extremity a roller 47, and the cam 43 bears against the roller 47 and is of such conformation of operative surface as to oscillate in one complete revolution any point on the shaft 44 and the segmental rack 45 through an are equivalent to that of the segment of the segmental rack 45. idly an arm 48, extending rearwardly and bearing pivotally at its extremity a vertical arm 49, which extends exteriorly of the frame 18 and on the same side thereof as the segmental rack 45, and the arm 49 bears at its lower extremity a weight 50, and the object of the weight 50 is to return the segmental rack 45 to the position from which it is moved by the shaft 19 and the cam 43.

Supported upon the upper portion of the frame 18 is another shaft 51, (best shown in Fig. 4,) which extends transversely of the frame 18 and is journaled in either side thereof. The shaft 51 bears a toothed gear-wheel 52 at one end thereof and exteriorly of the frame 18 on the same side thereof as the segmental rack 45, and the segmental rack 45 bears teeth upon the upper arc-shaped portion 53 thereof, meshing with the teeth of the gear-wheel 52, and the shaft 51 bears the dipping-frame and operates to dip it into the molten chocolate and return it to the apron 0, all as hereinafter described.

Referring to Figs. 4 and 6, the shaft 51 bears cylindrical heads 52, keyed at.either end, as at 53, and bearing slotted radial arms 54, (best shown in Fig. 3,) as at 55, and the arms 54 bear at their outer ends extensions or supplemental arms 56, which form the side supports of the dipping-frame, which is preferably composed of wire rods and cross-rods 57, hearing wire fingers or prongs 58 and hooked base-pieces of wire 59. (Best seen in Figs. 3 and 6.) The base-pieces 59 are movable vertically and have downwardly-bent rear portions which are hooked about rods 60, slidably mounted in vertical guides 61, secured to framemembers 62, extending transversely of the dipping-frame and secured to the frame members 57. The candy cores are placed in the dipping-frame upon the wire base-pieces 59 and between the fingers 58, and when the frame is lowered to discharge the coated candies the base-plate 59 will drop and tend to force the drops upon the endless apron O, and may also be made of any design, so as to imprint a mark or design upon the softcoated candies. I prefer to use wire in the construction of my dipping-frame for the reason that it insures maximum strength with minimum material, allowing of a thorough percolation of the molten chocolate through the frame and about the drops or candies.

The shaft 44 also bears rig- The weight 50, acting through the arm 48, holds the rack 45, and consequently the dipping-frame, in position for filling and jarring the latter, as shown in Fig. 3, the cam 40 being pressed against the uneven surface of the cam 43 by said weight.

With the machines now in use the manual handling of the drops or candy cores is necessary in filling the dipping-frame, and this is objectionable from a sanitary as well as economic standpoint. To obviate this, I provide a filling-frame, (best shown in Fig..3,) which comprises a frame composed of end rods or bars 60 and side rods or bars 61, and mounted upon tracks 62, extending on either side of the dippingframe in the position. shown in Fig.4, the bars 60 extending above and below the top of the tracks and forming flanges exterior of the track, obviating lateral movement of the frame. The track 62 is pr0- vided with a flat base 62 and is supported by standards 63. The verticallyarranged standards 63 are mounted in the upper members of the frame 18, as shown at 64, and threaded set-screws 65 pass through the frame and bind said standards 63 when the latter are adjusted at the right height.

Journaled in the end bars 60 of the fillingframe are a plurality of parallel shafts 66, mounted transversely of the frame 18 and bearin g interoperative gear-wheels 67 at their outer ends, respectively, in same side of the frame 18 as the segmental rack 45, and the gear-wheels 67 are exterior of the filling-frame and are of the same diameter. of the shafts 66 is an angular upwardly-extending arm 68, which bears a pin or projection 69, engaging a hooked portion of aspring 70, secured to one of the frame members 61 and exerting upward pressure against the pin 69, and by depressing said arm 68 theinteroperating gears 67 will be made to revolve alternately in opposite directions and the spring 70 will return them through reverse motions of the same extent, raising the arm 68 upon the shafts 66 and rigidly-mounted downwardly-looped hooks 71, preferably of wire, (best shown in Figs. 4 and 7,) and arranged oppositely to form pockets in series composed of two shafts 66'and their respec-. tive hooks 71. Into the pockets formed by the hooks 71 are dropped the candy cores, and the filling-frame is moved on the track over the dipping-frame, the angular arm 68 is depressed,and the candies deposited in the pockets formed by the fingers 58 and base-pieces 59. The filling-frame is then moved back to its position, as shown in Fig. 4.

As best shownin Figs. 3 and 4, a cross-arm 72 is mounted in the slots 55 of the radial arms 54 and bears a plurality of rods or bars 73, preferably of wire, which extend at right angles thereto and between guide-rods 74, parallel to the cross-arm 72, and the rods 73 are slidably mounted between said rods 74 and adapted to slide over and close the recepta'cles of the dipping-frame and act as retain- Fixed to one.

ing-rods for the candies therein during the dipping operation.

Referring to Fig. 3, is a lever-arm pivotally secured to a shaft 75, journaled in the upper portion of the cylindrical heads52 on either end of the shaft 51,.the dipping-frame being in the position shown in this figure, and it bears integrally a downwardly-projecting arm 7 6, approximately at right angles thereto and provided at the point of divergence with a catch 77, and said arm 75 is pivotally connected at its lower end with a short arm 78, which is pivotally connected with the end of the cross-arm 72. A standard 79 is mounted in the frame of the machine in proximity to said segmental rack 45 and preferably extends upwardly and rearwardly, so that the upper end shall project above said shaft 75 and in proximity thereto, and upon the upper end portion of said standard is pivotally mounted a catch 80, which has preferably a round body portion 81, over which is passed a curved band-spring 82, secured to the standard 79 at 83. The catch 80 is adapted to engage the catch 77 upon the revolution of the shaft 51.

Pivoted to the cylindrical head 52, as at 81, approximately diametrically opposite to the shaft 75, is a dog 84 of angular shape, the free extremity of which rests normally against the shaft 51 and which is provided, as at 85, (best shown in Fig. 4,) with a notch or recess which the outer end of the arm 75 is adapted to engage upon revolution of the shaft 51, and said dog 84: is provided in its inner angular portion with a pin 86, against which a spring 87, secured to the frame 18, as at 88, is adapted to bear upwardly. Pivoted to the frame 18, beneath the shaft 51, as at 89, is another angularpiece 90,which acts as a trip for the dog 84 and has an arm 91 extending upwardly and pressed against the shaft 51 by a spring-strip 92, secured to the standard 79, and the angular strip-piece bears at the apex an adjustable screw 93, which is adapted to come into engagement with alug or screw 93 on the inner face of the arc-shaped portion of the segmental rack 45, the frame 18 being cutaway in the path of said lug 93, as shown, and thus throwing the outer arm of the dog 84 outward from the shaft 51 and releasing the arm 75, which will fly upward, being connected with a spring 94, surrounding the shaft 75, being secured thereto and to the shaft 51, as shown in Fig. 1. The trippiece 90 is bent outwardly from the cylindrical head 52, allowing the dog 81 to pass under it in the revolution of the shaft 51.

As considerable of the chocolate or other liquid coating material in which the dippingframe is immersed will cling to the frame and catch in the receptacles thereof, I provide a mechanism for jarring the frame after its emergence from the liquid, comprising a spring-mounted rod (shown at 95 in Figs. 2, 3, and 1) extending transversely of the machine and beneath the rearward transverse member 57 of the dipping-frame. At the sides of and within the frame 18 are extensions 96 of the rod 95 at right angles there to and forwardly extending. Intermediately of said extensions 96 on the rod 95 are mounted blocks 97, keyed or pinned thereto and having slotted or grooved inner end portions in which, as at 98, are secured the ends of stiff bandsprings 99. The band-springs 99 are rigidly secured to the shaft 51 at their inner ends by means of a clamp, as shown in dotted lines at 100 in Fig. 4. The projections 96 of the rod 95 therefore project forwardly, and forward of their outer ends is mounted a shaft a, (best shown in Fig. 2,) extending transversely of the frame 18 and suitably journaled therein and bearing toothed wheels a opposite the ends of the extensions 96 of the rod 95, and the wheels a have teeth a adapted to engage said extension ends, the

hearing or engaging surfaces of which, as well as of the teeth (F, are preferablycurved or beveled to facilitate the release of said extension ends after the engagement of each tooth c (Best shown in Fig. 3.)

On the end of the shaft 19 opposite to tha which bears the cam 43 and exterior of the frame 18 is loosely mounted a toothed wheel a. (Best seen in Fig. 2 and shown in dotted lines in Fig. 1.) The toothed wheel a is geared in connection with a toothed wheel a secured to the end of the shaft a exteriorly of the frame and on the same side of the ma chine as the wheeled. The wheels (1 and a are geared together by a sprocket-chain a engaging the teeth thereof. The wheel a has a flat hub A, (best shown in Fig. 9,) to one side of which are secured dogs a a of angular shape and pivoted centrally, as at a b, so that their end portions come into contact with the shaft 19, and the inner edges adjacent to the shaft 19 are curved in arcs greater than the peripheral curve of theshaft 19, through whichon the same side of the hub A or that to which the dogs a a are pivoted passes a key or pin 5 and springs b secured to the hub A, exert pressure on the end of each of the dogs a a which ends in the revolution of the shaft in the direction indicated by the arrow in Fig. 9 would be successively presented to the pin or key b an end of which projects from the shaft 19 over the face of the hub A.

Secured to the frame 18, adjacent to the wheel A, is a lug b bored and threaded to receive a threaded adjusting-screw b which is adapted to bear on the dogs a" a on the end portion 1) which do not engage the pin 6 and the function of the screw 17 is to suecessively release the dogs a c from the pin in the revolution of the wheel a which thus is in the direction of the shaft 19 and, as will be seen, occurs intermittently, imparting motion to the shaft a and vibrating the rod 95. The adj Listing-screw b may evidently vary the duration of the impulses imparted by the shaft 19 to the wheel a and the intermittent movement of the wheel a, is regulated to furnish power for vibrating the jarring-' rod 95 only when the dipping-frame is in certain position, as hereinafter described.

Mounted interiorly of the frame 18 in the forward portion and beneath the dippingframe is the chocolate-reservoir b (shown in dotted lines in Figs. 1 and 3,) having a curved bottom portion and surrounded by a tank 19 (shown in dotted lines in the same figures,) and the tank is adapted to be filled with hot water to keep the chocolate in the reservoir 11 in a liquid condition. A faucet b in the forward end and at the bottom of the tank 6 serves as an outlet for the water therein, and both the reservoir and tank may be filled from the top. \Vhen the dippingframe is filled with candy cores, it is dipped in the reservoir Z9 by the revolution of the shaft 51, as described. The counter-revolution of the shaft 51 by the return movement of the segmental rack 45 swings the dippingframe over to inverted position on the endless belt or apron O, which moves the coated chocolates deposited thereon through a refrigerator hereinafter described. v

The molten chocolate in the chocolate-reservoir will gradually thicken at the bottom of said reservoir and become too thin through-- out the reservoir. To advoid this, an agitator (best seen in Fig. 13) is provided mounted on a shaft B, extending transversely ofsaid reservoir and journaled in the sides thereof, as at B. This agitator bears radial blades 13 having perforations B the whole adapted to keep the liquid chocolate thoroughly agitated and mixed. The shaft B bears fixedly at the end nearest the side of the frame 18 at which the sprocket-wheel a is located a sprocket-wheel B and in the same side of the frame 18 and above the sprocket-wheel B is journaled a short shaft B which bears at either end fixed sprocket-wheels B and B?, respectively within and without the frame 18, and the sprocket-wheels B and B are suitably geared together by a sprocket chain B -Upon the end of the shaft 19, exteriorly of the frame and of the sprocket-wheel a, is a fixed sprocket-wheel B and the sprocketwheels B and B are suitably geared together by a sprocket-chain. (Not shown.)

The endless belt 0 is supported by a series of rollers about which it passes, and which is as follows: A roller 0 is jonrnaled in the frame 18 at either side thereof, extending transversely across the same and in a vertical plane longitudinally of the frame 18, which is forward of the dipping-frame when the same is inverted to discharge the coated candies. Another roller C is at the rear end of the frame 18 and mounted similarly and parallelly to the roller 0 Another roller 0 a and provided with a binding-screw D sion-roller hanging on the lower portion of the belt 0, which extends in an unbroken oval endless curve about the said rollers (J and C The roller 0 bears fixedly at its end exteriorly of the frame 18 and on the same side thereof as the segmental rack 45 a ratchet-wheel O and interiorly of the ratchetwheel C is pivotally mounted to the roller 0 a pawl-arm O extending therefrom and the teeth of the ratchet-wheel O and the end of the arm 0 which supports the pawl D, is pivotally connected to the rod or arm D as at D and the rod D extends forwardly of the frame 18 and exteriorly thereof and pivotally engages a connecting-link D and a lever-arm D pivoted intermediate of its ends, as at D to the frame 18 and bears at its lower extremity a roller D and the other end thereof passes through the link-rod D which is longitudinally adjustable thereon lever D may be adjusted in the connectinglink D and when adjusted secured in position by the binding-screw D of any desired construction, and the object of the adjusting of the connecting-link D is to allow of altering the throw of the rod D Loosely mounted upon the shaft 19, exteriorlyof the cam 43, and shown best in Fig.

1, is a cam 6, having a projection or arm 6 and the cam e is adj ustably secured to the cam 43 by an adjusting-screw c and theprojection e is hook-shaped and engages at the proper moment in the revolution of the shaft 19 with the roller D on the lever-arm D and throws the rod D moving the ratchet-wheel C and the apron C, and the spring 0 and the pawl -arm 0 returnthe rod 0 and pawl D.

The refrigerator is mounted upon the rear portion of the frame 18 and above the belt or apron C, and shown differently in Figs. 1, 2, 3, 4, 7, and 8, and comprises a casing e preferably of wood, and is provided at its forward The end with a vertically-adjustable wall e (best shown in Fig. 7,) sliding at its side portions behind flanges or cleats a on the sides of the refrigerator and having gear-plates e in proximity to said cleats, and a shaft or rod extends across the front of the refrigerator and is journaled at said cleats and bears gearwheels F ,operating with said gear-plates,and an operating-wheel F at one end, whereby said vertically-ad j ustable wall e may be raised or lowered. lower edge portion a hinge F, by which is supported a flap-door F, which may be lowered down upon the apron C by the adjustable wall 6 and is adapted to move inwardly of the refrigerator and bears adjustable con- The wall 6 bears at its plates and bind it in any adjusted position best adapted to receive the outer end of the frame member 56 of the dipping-frame upon the lower ends F thereof and to swing said flap-door inwardly over the apron O and allow of the deposit of the coated chocolate drops on said apron. F are springs secured to said wall 6 and passing over the upper ends of the contact-plates which project above the hinge F and tend to keep the flapdoor F closed.

The rear end wall of the refrigerator, as shown in Fig. 8, has an opening at the bottom over the apron C, and above said opening is a flap-door G, hinged to the refrigerator by a hinge or rod G. The flap-door G carries a projecting and forwardly-curved arm G having a slot G through which passes an adj Listing-screw G fitted to the refrigerator end, and by the adjusting-screw G the flapdoor G may be opened at the predetermined angle necessary to allow of the exit of the coated drop from the refrigerator.

A support G is fixed to the rear end of the refrigerator and extends therethrough and is bored longitudinally to receive a shaft F, to the inner end of which is fixed a fan G and to the outer end a pulley g \Vithin the refrigerator are ice-chests G preferably two, as shown in dotted lines in Fig. 8 and partiallyin Fig. 1 in full lines, supported by hooks G secured to the ends thereof and fitting rods G extending across the refrigerator near the top thereof. The iceboxes G are of greater vertical cross-section at the middle portions than at the ends, and the inner sides thereof are separated, as at 9 and of much less vertical extension throughout than the outer sides G at their lines of greatest vertical extension. All the sides and faces of the ice-boxes G are preferably plane and straight. By the construction described the ice-boxes G have a lowest portion at the middle of the outer sides thereof, and said lowest portions are fitted with waste-pipes ll, communicating with the interior thereof and adapted to carry away the water. Below the ice'chests is a drain-compartment ll, extending across the refrigerator and secured in any suitable way to the sides thereof and having an open space between either end thereof and the ends of the refrigerator. The compartment H is of diminished vertical section at its middle portion and has openings in its upper surface with which the pipes H communicate and waste-pipes H at the side to discharge the water received from the ice-boxes G at the sides of the apron C, and the sides and faces of the compartment H are all preferably plane and straight.

and may be removed to place ice in said icechests.

The sides of the refrigerator are closed and the bottom open, as described. The fan G6 is adapted to revolve and agitate the air in the refrigerator and keep it circulating below A lid H fits the 'open roof or upper side of the refrigerator constantly subjected to a cool draft of air.

The machine is preferably furnished power by means of a main belting H, (shown in Fig. 8,) which turns the pulley 39 in the direction denoted by the arrow shown in Fig. 8, and said belt returns from the pulley 39 about the guide-pulley H mounted in the frame 18 at the opposite side thereof. A pulley H is mounted above the pulley H and fixed on a short shaft jonrnaled in the frame 18, which bears another pulley Hhand the belt H engages the pulley H as it passes to the pulley 39 and turns the pulley IF. A double pulley H is mounted on the rear end of the refrigeratorcasing, and over it runs a belt H which is run by the pulley H and the double pulley H supports upon its larger circumference H a belt H, which engages and runs the pulley g turning the fan G.

A pan K is supported at the front of the machine by a frame K, having a hooked rear member passing over a rod K supported by the frame 18 and under lugs or strips K The pan K holds the candy cores or bodies to be piaced in the filling-frame. A pan L is supported at the rear end of the machine by a support L, secured to the frame 18, and a scraper or guide-plate L is pivoted to the frame 18 under the flap-door G and is pressed against the belt 0' by a spring L secured to the frame 18, and the outer lower end of the guideplate L is suspended over the pan L and is adapted to lift'the finished candies from the belt 0 and guide them into the pan L. The scraper L also acts as a scraper and scrapes the waste chocolate from the belt O and deposits it through a slot L into a cup L The operation of this machine will be readily understood fromthe foregoing description, when taken in connection with the accompanying drawings and the following statement thereof.

The candy cores are taken from the pan K and placed in the pockets formed by the hooks 71 of the filling-frame, and the fillingframe is moved along the track 62 until over the dipping-frame, which latter will be in the position shown in Fig. 3. The lever-arm GS is then depressed, and the cores will fall into the pockets formed by the finger 58 and base-pieces 59 of the filling-frame. The dipping-frame is then ready to be dipped into the chocolate-reservoir b and the machine is started by depressing the treadle 20, which draws down the cord 20, operating the rod 29, and lever 34, operating the clutch 35 and coupling the shaft 37 with the pulley 39 and which is run by the belt H. Simultaneously the roller 26 is withdrawn from the recess 28 in the collar 27, and the shaft 19 is unlocked, and the worm-gear 41 immediately begins to turn said shaft in the direction indicated by the arrow in Fig. 1.

Due to the shape of the cam 43, as shown in Fig. 1, the roller 47 at the outer extremity chain 1) and sprocket-wheels Z2 and U and of the cam '46 is borne downwardly in contact with said cam 43 by the weight 50, connected with the arm 43, and the segmental rack 45 revolves the gear-wheel 5:2, which it engages, and also the dipping-frame shaft 51, depressing the filled dippin g-frame toward the chocolate-reservoir b Referring to Figs. 3 and 4, as the dipping-frame moves downward the lever-arm 75, pivotally mounted on the shaft '75 by means of the catches 77 and 80, is depressed and engages with the notch or recess 85 in the dog 84 and is locked thereby, the arms 76 and 78 being thrown forward, moving the cross-arm 7 2 forward and the retaining-rod 7 3 over the pockets or receptacles in the dipping-frame to retain the candy cores in position during the dipping movement.

- When the dipping-frame has reached the limit of its downward movement, the shape of the cam 43 (seen in Fig. 1) causes the cam 46 to reverse its movement, and it and the Weight 50 are raised and the shaft 51 reversed in its movement and the dipping-frame moved in a wide ascending arc and brought over in its descent onto the apron C at its forward upper portion, and at this time the lug or screw 93 on the segmental rack 45 (shown in Fig. 1) strikes against the adjustable screw 93 on the trip 90, (shown in Fig. 3,) and during the rearward movement of the dippingframe'the lever 75 and dog 84 have ridden under the bent trip-piece 91, and said trippiece now engages the outer end of the dog 84 and forces it againstthe spring 87, releasing the lever-arm 75, which is thrown upward by the spring 94 in the shaft 51, withdrawing the cross-arm 7 2 and the retaining-rods 73 and allowing the coated chocolates to fall out upon the belt or apron G, as seen in Figs. 3 and 7. This operation is assisted by the slidably-mounted rods 60, which are connected with the base-pieces 59 and which fall upon or press the drops, forcing them out should they stick and imprinting a symbol or mark upon them, if desired. The jarring-rod 95 is so controlled in its operation by the toothed wheels a and the loosely-mounted toothed wheel a (seen in Fig. 9) and operating in connection therewith that the extensions 96 of said jarring-rod shall not be vibrated by the toothed wheel a when jarring-rod and extensions, due to the movement of the dippingframe, would be driven against the dippingframe and broken. This latter might otherwise occur just after the dipping-frame left its position, as shown in Fig. 3, to be dipped and just before renewing said position after being dipped. The jarring-rod is therefore vibrated when the dipping-frame rests in a horizontal position, as shown in Fig. 3, and just after it .has emerged from the chocolatereservoir. The agitator (shown in Fig. 13) mounted in the chocolate-receptacle is in continuous operation during the motion of the shaft 19 through its connection therewith by the sprocket-wheels b and l) and sprocketsprocket-chain b )Vhen the dipping-frame has reached the belt or apron C, the extension members 56 thereof press against the ends f of the contact-plates F as'shown in Fig. 7, and open inwardly the flap-door F of the refrigerator, the vertically-movable wall 6 being at the proper height, and the coated drops are placed upon the belt or apron C,

and the dipping-frame returns to the position shown in Fig. 3, the shaft 51 being re roller, 26 in the recess 28 of the collar 27 (shown in Fig. 1) the arms 6 of the cam e engage the roller D of the lever D and force the rod 1) forwardly, the roller D riding over the outer curve of the extension 6 of the cam e to operate the pawl-arm C and the pawl C and turn the ratchet-wheel C), the roller moving the belt so as to draw the coated I candy drops into the refrigerator. \Vhen the machine is again started, the lever-arm D will be sprung back into the position shown in Fig. 1 by the spring 0 attached to the pawl-arm C during the movement of the belt H, which is operated by any suitable engine or other means, the power being transmitted thereto bythe belts H and H and pulleys H H H H and g, the directions of motion of said pulleys being indicated by arrows in Fig. 8. When the roller 26 rides into the recess 28 in the collar 27, being pressed therein by the spring 32, the clutch mechanism is operated to withdraw the clutch and disconnect the shaft 37 and the pulleys 39, stopping the revolution of the worm-gear 41, the machine being at rest with its parts in the position shown in Fig. 1. \Vhen the belt 0 is full of coated drops, those which have advanced farthest toward the rear end of the refrigerator are sufficiently cooled and hardened and pass under the flap-door G, which is suiiiciently opened, and the guide-plate L guides them into the pan L.
